Toyota Tunda Sumo springs install 

I am running them on my 2015 tundra and they are fantastic, it is very important to note that you are NOT supposed to re-use U-bolts, they are one and done, and stretch under the first torque, so they cannot get re-torqued to spec. Failure is very rare, but pretty horrible considering the cost of replacement ubolts. rear bolts need to be torqued to 90 ft/lbs

Thank you for your video. Perfect execution. Detailed and quick. I'm subscribing.

Amazingly helpful video, as your follow up was too. THANK YOU!!!

Another helpful tool would be a clamp to clamp the new u-bolts with your new sumo springs. Sometimes the u-bolt could be a little wide for the bottom bracket for the u-bolt to go through the holes.

In addition to the Sumo Springs, try adding the TRD Sway Bar, makes a world of difference when towing 9,000 lbs.

I put the yellow color on my '02 Tundra. I thought they were great. 1 ton no sweat. With fat sway bars it was a bit rough with the yellow color bumper. It cornered like a sports car though. Blue is what I'll add to my '21 rather than the heavier yellow..after 36k.

Does it change the ride smoothness?

How do these compare to air bags or helper leaf springs? I have a 2006 tundra that I would like to reduce sag on. Assuming this would do the job?

I see you used a jack under the axle, you did not have any issues with compressing the spring for installation?
